Validating the System
Validating the System
•
What is the academic basis to the Insights Discovery system?
•
Has the Insights Discovery system been validated by official bodies of the psychology profession?
•
Is the Insights Discovery preference evaluator continually tested and updated?
Insights and Jung
External Assessment
The Insights Discovery System is solidly
based on the psychological types theory of Dr
Carl G Jung and one of his leading students,
Dr Jolande Jacobi. Jung proposed that our
personalities are created in the interaction
of four functions and two attitudes. When
combined, these elements generate eight
common personality types. Jung felt that what
makes an individual unique are the different
balances of these functions and attitudes
interacting within them. It is these balances
that make up the Insights 4 Colour System.
The four colours represent observable
behavioural patterns:
In 2005 the University of Westminster’s
Business Psychology Centre performed an
extensive study of the Insights Discovery
Evaluator English Version 3.0. Key statistical
analysis was used to study the IDE’s “item
analysis”, “norm data”, “reliability” and
“validity”.

Insights Discovery©: Validating the System
Item Analysis
There are 100 colour items spread over the
25 frames in the IDE. Item analysis involves
empirically testing the quality of these 100
items and replacing weaker items with better
ones. This is measured by assessing the
responses of participants with clear colour
preferences, i.e. those whose average across
all 25 frames is greater than 5 in one out of the
four colours (“Sunshine Yellow, “Fiery Red”,
“Earth Green” or “Cool Blue”). Figure 3 shows
one of the improvements made in the items
from IDE S1.0 (UK) to IDE S2.0 (UK).
Figure 3: Example of results
of item analysis - graphs show
‘before’ and ‘after’ item changes
Note: Green scoring higher than
yellow on a yellow item before
the alteration.

As expected, those in charge of financial
data tend to have a preference for objective
thinking, using facts and performing detailed
analysis. It should be noted whilst this data
indicates that people in certain roles tend to
have a preference for certain colours, it does
not correlate or necessarily relate to how well
they are doing their job or how capable they
are in fulfilling that role.
Reliability
Cronback-Alpha coefficients, α, measure
the error variance on the average inter-item
correlations. When the error variance is
low, which is desirable, the alpha coefficient
approaches 1.00. A value of 0.70 is the
commonly accepted inferior limit.
Analysing 24,224 completed evaluators shows
the four colours to have very high CronbachAlpha coefficients, providing evidence of
reliability as shown in Table 1.

Confirmatory Factor Analysis was used to
test the hypothesised factor structure of the
Insights Discovery model. Specifically it is
hypothesised that the four sets of 25 colour
based items in the IDE should load onto the
factors such that the polar opposite nature
of the ‘Fiery Red’ vs. ‘Earth Green’ items is
apparent and the polar opposite nature of
the ‘Sunshine Yellow’ vs. ‘Cool Blue’ items is
apparent. The four colours should load onto
their appropriate factor only.
The results in Table 2 successfully confirm this
hypothesis.
Conclusion
Over the past decade, the work of Carl Jung
has attracted increasing interest as people
seek to improve interpersonal dynamics on
both personal and professional levels. The
scientific research of the Discovery System
demonstrates that both Jung’s original
typology theory, and Insights’ ongoing research
to enhance it, has both strong psychological
foundations, and modern scientific application.
Depth psychology and empirical science unites
within the Insights Discovery System.
